ABOUT MELook_its_me.jpg


Hey whats up! I enjoy sitting on couches with people, and watching movies. After I graduate I plan on going to college for four years to be able to pursue my career as a nurse anesthetist. I prefer winter over summer for many reasons. I would rather be cold when I'm sleeping, and snow is the greatest thing ever! Other than the typical winter qualities, my favorite holidays are also in winter. If I had to choose one country to invade America it would definitely be China because Chinese food is freaking awesome! I love to listen to music all the time especially when I'm working or doing . I'm not very interested in school unfortunately, but bio looks very promising and I'm looking forward to a good year.

Classification of Marine Bacteria


1. How charming! You are Lamprocyclas maritalis!
This attractive microbe is a type of radiolarian that constructs beautiful, complex shells of silica (glass). Like you, L. maritalis also stays up late; this microbe actively preys day and night. L. maritalis also shares your sense of organization and tidiness. Its cell contents are packaged in organelles; for example, its DNA is neatly contained within a nucleus. Like your straight hair, this microbe has straight extensions from its shell that help protect it from predators.

2. A- The key asks you to questions, which lead to more questions to determine what microbe you are.
B- To discover what people are similar to you.
C- What you are like such as, how you act, what you like, and things you do in general.
D- Lamprocyclas maritalis!
E-Synechococcus

Biomolecules


1. After doing the experiment my results turned out to be pretty high compared to others.The enzymes had a stronger reaction compared to other foods tested. I've learned that surprisingly that not very food have strong reactions to the hydrogen peroxide. I also learned that enzymes play a important role in combining molecules together to react. If an enzyme is heated the shape changes and the molecules cannot combine, therefore, there is no reaction. Catalase in food is important because it helps to break down food.

3. What happens to an enzyme when it is heated? - If an enzyme is heated the shape changes also known as denaturing. The enzyme will not be able to function anymore, therefore, the small molecules will not fit. Without the enzyme the molecules will not react.

1. Cannelini Beans- starch, fat, protein.
2. Peas have starch and fats present, which means the catalase reaction is the same. Milk has starch and protein present, which means the catalase reactions are the same. Potatoes have starch and fat, which means the catalase reactions are the same.
3. Depending on the temperature of the hydrogen proxide, the more it effect the enzymes inside the reation.


Chromatography




Screen_shot_2011-01-16_at_9.45.12_PM.png

The lab results show that different plants had similar Rf values and shared the same color. The color would be the pigment and since they have that same color they also have the same chlorophyll. Plants a and g(bottom) have the same Rf value in pigment 2 and same color meaning they have the same chlorophyll.

Light intensity- generally is obtained by dividing a power, in watts by a solid angle, a planar area, or a combination of the two. It really is the first part of photosynthesis because light is needed for energy to be absorbed. So the intensity of it depends on how close or how much sunlight a plant is getting.


Wavelength and energy- the amount of energy is inversely related to the wavelength of the light: the shorter the wavelength, the greater the energy of each proton of the light. Max Planck who identified a co-efficient of proportionality that related photons energy to its frequency discovered this.


Pigment color- a pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. The chlorophyll organelle in plants contains green pigment and chromoplasts contain different pigments that show in the fall season.


1. Wavelength and light intensity is important for photosynthesis because they are dependant variables, which means that what happens with one changes the other. The greater the light intensity the less wavelength etc. In the simulation this showed that if we change one variable the other has to change as well to produce enough ATP as possible.
2. I learned that a higher light intensity is vital because if a plant has more sunlight then photosynthesis will go by much easier. That’s why we put a plant in front of a windowsill so it can get as much light as possible. The greater the light intensity the less the wavelength will be and vise-versa.

1. The height of rise in the bread solution is dependent to the amount of sugar concentration. We used warm water because it works better in the reaction. During the reaction carbon dioxide is released, which causes the balloon to rise.
2. The dependent variable would be how much the bread rises. The independent variables would be the temperature of the water, and the sugar solution. The yeast reacts differently depended on your sugar solution and temperature of the water. Different sugar solution have more or less rise in their balloons.
3. Yeast prefers warmer temperatures of water. The sugar concentration changed the results only by causing a slight larger reaction causes more carbon dioxide to fill up the balloon.
4. The four concentrations very in reaction. They each had a different concentration, and the higher the concentration the greater the reaction.
5. Anaerobic respiration is carried out by the yeast. Alcohol fermentation occurs when the yeast ferments, and when this happens the carbon dioxide is released.
DNA Model Project

Step 1:

Step_1.jpg

In the first step there is a single DNA molecule which can be then made into two DNA molecules by mitosis or meiosis.


Step 2:
Step_2.jpg

In the next step the DNA molecules hydrogen bonds are broken apart by DNA helicase.

Step 3:
Step_3.jpg

Now you have a left side and a right side of the DNA molecule. The left gets a new right and the right gets a new left.

Step 4:
Step_4.jpg

This shows the two sides merging together to form two strands of DNA. A pairs with T and C pairs with G. DNA polymerase allows the new strands to bond with the original strand.

Step 5:
Step_5.jpg

This is the end product of DNA replication. Two similar strands of DNA are made for mitosis or meiosis.

In DNA replication a single strand of DNA is split through its bonds by DNA helicase. The left and right side each get a strand that matches it such as ACTTGA. The new strand would have to be TGAACT. Left gets a new right and the right gets a new left. They merge together by DNA polymerase to form two exactly alike pairs of DNA strands. In the end we end up with two similar strands of DNA. The process can occur again and you would end up with 4, 8, 16, 32 etc. DNA replication occurs during the interphase stage of mitosis.

Class Traits



You can have 2 types of thumbs when you are born. You can have a hitchhiker’s thumb that is the recessive trait, and a straight thumb that is the dominant straight. In an internet survey 15 people had a straight thumb out of a total of 21. In another survey 12 people had a hitchhiker’s thumb out of a total of 17. You would think the hitchhiker’s thumb is dominant according to the surveys, but it isn’t. Some people can also have dimples. Having dimples is a dominant trait, making not having dimples the recessive trait. In an internet survey 6 people had dimples out of a total of 24. In another survey 138 people did not have dimples out of a total of 184.

In conclusion the surveys from the internet are very similar to our classes’ trait survey. The classes’ survey states that 10 people out of 24 had hitchhiker’s thumb. Having a straight thumb is the dominant trait so that wouldn’t seem uncommon. In our class 14 people out the 24 have dimples. Having dimples is the dominant trait again having similar results with the internet survey.

In our class the number of girls with a widow’s peak is 2, and boy 4. A total of 6 people out of 24 have a widow’s peak. Having a widow’s peak is the dominant trait, and not having the widow’s peak is the recessive trait. Another trait that is surprising is having freckles. Out of 24 people in our class only 1 person has freckles. No girls in our class have freckles only 1 boy. Having freckles is actually the dominant trait, and not having them is the recessive trait.

Out of my family only my father cannot roll his tongue. Being able to roll your tongue is a dominant trait. Even if both of your parents cannot roll their tongue their child still may be able to. My mother has the dominant trait and her genotype would be TT or Tt and my dad Tt. My phenotype would either be TT or Tt since my mother has the dominant trait and my dad the recessive.
